"The Qing Dynasty was the result of the successful Manchu conquest of China. A banner system was invented to organize the Manchu armies and played a key role in the unification of the Jurchen people. Additional Mongol and Chinese banner armies were further assimilated into the Qing military."

Due to its fast attack speed, this unit fares well against infantry, as their lower health means that more shots that do less damage, which the Manchu Riflemen has, does better as less shots are wasted. Against other defenses, such as cavalry, towers and traps, you'll treat them like a regular shooter; keep them out of fire, target the defenders, etc.

Manchu Riflemen have low health; making them vulnerable to defenses. Use Heavy Infantry such as Shock Infantry as meat shields to protect the Manchu Rifleman.

Manchu Riflemen are cheap and can be used to set off hidden enemy traps.

Use Manchu Riflemen to protect heavy infantry from other infantry so your heavy infantry won't get distracted.

Manchu Riflemen can be used as good Alliance Troops. One example is that they can shoot over walls to attack troops of the attackers forcing the troops to destroy the wall to kill them. Another thing is that they're good against other heavy infantry.
